Abstract

A system for automated operation of a host-vehicle includes a controller configured to operate the host-vehicle during automated operation of the host-vehicle. The controller is configured to do so in accordance with a parameter stored in the controller. The controller is also configured to determine when an operator of the host-vehicle uses a vehicle-control-input to override the controller and thereby operate the host-vehicle in a manner different from that which is in accordance with the parameter. The controller is also configured to modify the parameter in accordance with the manner of the operator.

First claim

We claim:

1. A system for automated operation of a host-vehicle, said system comprising:
a controller configured to operate the host-vehicle during automated operation of the host-vehicle and do so in accordance with a parameter stored in the controller, determine when an operator of the host-vehicle uses a vehicle-control-input to override the controller and thereby manually operate the host-vehicle in a manner different from that which is in accordance with the parameter, and modify the parameter stored in the controller for use by the controller during future automated operation of the host-vehicle, wherein the parameter is modified based on the manner of the operator.

2. The system in accordance with claim 1 , wherein the vehicle-control-input includes a brake-pedal, an accelerator-pedal, and a steering-wheel operable to override the controller.

3. The system in accordance with claim 1 , wherein the system includes a turn-signal lever, a switch, and a microphone operable to instruct the controller to modify the parameter.

4. The system in accordance with claim 1 , wherein the system includes
a detector configured to detect a distance to an object proximate to the host-vehicle and provide a distance-signal to the controller indicative of the distance, and
the controller is configured to operate the host-vehicle in accordance with the distance-signal and a minimum-distance-parameter, wherein the controller modifies the minimum-distance-parameter when the operator overrides the controller and operates the host-vehicle in a manner that prevents the controller from operating the host-vehicle in accordance with the minimum-distance-parameter.

5. The system in accordance with claim 4 , wherein the minimum-distance-parameter includes a forward-minimum-distance, a rearward-minimum-distance, a leftward-minimum-distance, and a rightward-minimum-distance.

6. The system in accordance with claim 5 , wherein the controller increases the forward-minimum-distance of the minimum-distance-parameter when the operator presses a brake-pedal while the distance-signal indicates that a forward-distance to the object is greater than the forward-minimum-distance.

7. The system in accordance with claim 5 , wherein the controller decreases the forward-minimum-distance of the minimum-distance-parameter when the operator presses an accelerator-pedal while the distance-signal indicates that a forward-distance to the object is not greater than the forward-minimum-distance.

8. The system in accordance with claim 4 , wherein the detector is further configured to determine a classification of the object, and the controller selects the minimum-distance-parameter based on the classification of the object.

9. The system in accordance with claim 8 , wherein the classification of the object includes a vehicle-size, a vehicle-type, a roadway-structure, and a lane-marking.

10. The system in accordance with claim 1 , wherein the system includes
a path-planner device used by the controller to select a host-travel-lane for the host-vehicle based on a lane-preference-parameter, and the controller is configured to modify the lane-preference-parameter when the operator operates the host-vehicle to steer the host-vehicle into a different-lane.

11. The system in accordance with claim 10 , wherein the lane-preference-parameter for a three-lane roadway is initially set to right-lane, and the lane-preference-parameter for a three-lane roadway is modified to center-lane after the operator overrides the controller by moving the steering-wheel to steer the host-vehicle from a right lane of the three-lane roadway to a center lane of the three-lane roadway.

12. The system in accordance with claim 10 , wherein the lane-preference-parameter for a three-lane roadway is initially set to right-lane, and the lane-preference-parameter for a three-lane roadway is modified to center-lane after the operator instructs the controller by operating the turn-signal lever to steer the host-vehicle from a right lane of the three-lane roadway to a center lane of the three-lane roadway.

13. The system in accordance with claim 1 , wherein the system includes
a path-planner device used by the controller to select a host-travel-lane for the host-vehicle based on a lane-preference-parameter.

14. The system in accordance with claim 13 , wherein the controller is configured to modify the lane-preference-parameter when the operator operates a turn-signal lever to instruct the controller to modify the lane-preference parameter.

15. The system in accordance with claim 13 , wherein the controller is configured to modify the lane-preference-parameter when the operator turns the steering wheel to override the controller and thereby instruct the controller to modify the lane-preference parameter.

16. The system in accordance with claim 13 , wherein the path-planner device is used by the controller to execute an anticipatory-lane-change based on an anticipation-distance-parameter, and the controller is configured to modify the anticipation-distance-parameter when the operator operates the host-vehicle to steer the host-vehicle in a manner that is not in accordance with the anticipation-distance-parameter.

17. The system in accordance with claim 1 , wherein the controller is configured to operate the host-vehicle to enter an intersection while waiting to make a left-turn based on an intersection-left-turn-parameter, and the controller is configured to modify the intersection-left-turn-parameter when the operator presses the brake-pedal to prevent the host-vehicle from entering the intersection while waiting to make the left-turn.
